T Coronae Borealis could erupt any day, visible without telescope
Technology
Heads up, space fans: astronomers say the star system T Coronae Borealis (T CrB) could burst into a bright nova any day now.
If it happens, you will be able to spot a new star in the night sky without a telescope: a super rare chance for anyone who loves stargazing.
T CrB could match Polaris brightness
T CrB is a recurring nova that erupts about every 80 years, thanks to its white dwarf pulling material from a red giant neighbor.
The last explosion was way back in 1946. This time, T CrB could shine as bright as Polaris for about a week.
To catch it, look for Epsilon Coronae Borealis in the semicircular cluster and scan one degree to the lower right.
This cosmic show will not come around again for decades.
